Motor-bearing stress from variable‑speed drives is a clear MRO cost driver; specify shaft‑grounding or bearing isolation as standard spare items and include them in work packs to reduce repeat failures

Key takeaways

Motor-bearing stress from variable‑speed drives is a clear MRO cost driver; specify shaft‑grounding or bearing isolation as standard spare items and include them in work packs to reduce repeat failures.[1]
Valves, sensors and ‘last‑metre’ instrumentation materially affect energy, water and uptime performance; treat valve spares, calibrated sensors and commissioning scope as lifecycle buys rather than one‑off purchases.[2]
Measurement devices degrade trust when diagnostics and verification are absent; add diagnostic health checks and sensor replacement criteria into preventive maintenance and spare plans.[3]

Why this matters for the category manager

These themes are recurrent across industry guidance — the practical takeaway for procurement is to convert technical fixes (shaft grounding, valve lifecycle, device verification) into contract and stockline requirements

What changed

Added a concrete sourcing emphasis on motor‑bearing protection (shaft grounding/insulation) and valve/instrumentation lifecycle spares compared with the prior brief's focus on edge compute and automation spares.

Category impact

Cost / money

Specifying shaft‑grounding devices and insulated bearings increases upfront spare part spend but lowers recurring bearing replacement and labor costs by preventing electrical damage to bearings.[1]
Treating valves and sensors as lifecycle items shifts budget from ad‑hoc reactive buys to planned stocking and calibration budgets, changing Opex timing and contract pass‑throughs.[2]

Supplier / commercial

Requiring preinstalled grounding or packaged motor options can change supplier quoting posture — vendors may quote higher unit prices but shorter lead times or bundled installation services.[1]
Specifying lifecycle support (commissioning, calibration, spare lists) creates negotiation leverage to obtain separable pricing for hardware versus service renewals.[2]

Safety / operations

Motor shaft currents and bearing failures are an operational safety and uptime risk; adding grounding/isolation reduces unplanned downtime and repeat corrective maintenance work.[1]
Poor instrumentation health degrades control performance and can increase process variance; formal verification and replacement criteria support safer, more consistent plant operation.[3]

What to watch

Some recommended fixes (shaft grounding devices, insulated bearings) have size or supplier constraints that may limit local availability; verify distributor stocking rather than assuming ready supply.[1]
Vendor technical guidance sometimes omits lifecycle cost for commissioning and calibration; watch for bundled offers that hide recurring service pass‑throughs unless contracts force separable line items.[2]

Source excerpts

Adding a shaft grounding device to the motor prior to installation (or buying a motor with one preinstalled) can be a small price to pay when compared to the price tag of maintenance costs associated with bearing replacement, not to mention the high costs of downtime in a facility. There are several common types of shaft grounding devices in the industry today, such as carbon brushes, ring-style fibre brushes and grounding bearing isolators; and other methods of protecting the bearings are also available

Ceramic bearings Another way to prevent a discharge of current through the bearings is to manufacture the bearings from a nonconducting material. In ceramic bearings, ceramic-coated balls protect the bearings by preventing shaft current from flowing through the bearings to the motor

On motors larger than 75 kW, it is generally recommended that an insulated bearing be installed on the opposite end of the motor on which the shaft grounding device is installed, regardless of which style of shaft grounding is used. Table 1: Pros and cons of shaft grounding methods

More consideration needs to be given to the full instrumentation and valve lifecycle, from installation through commissioning, maintenance, optimisation and, when needed, replacement, so that a plant’s performance in year 10 is equivalent to year one

Because in the end, a valve is never just a valve

More consideration needs to be given to the full instrumentation and valve lifecycle, from installation through commissioning, maintenance, optimisation and, when needed, replacement, so that a plant’s performance in year 10 is equivalent to year one. From a sustainability perspective, this matters as much as any new ‘green’ announcement
